This includes an instructional poster to show a whole number in the millions written in standard form, written form, and expanded form shown in 2 ways. There are 5 empty copies of this that you can use as you instruct and practice. You could simply print and have 5 sheets available as a formative assessment. Students could roll a die a set number of times and then use this to build a number. They can then fill in the graphic organizer as they show you their understanding of it.
